Sugar Cube Melon Questions

What's up fellow Gardners! This was my first attempt at growing sugar cube melons (northeast region) and I have some questions:

  • Should I be concerned about the exterior being so scorned?
  • The leafs just started developing disease this past week, will the fruit still get it's nutrients and continue to grow?
  • I know these melons are smaller, when can I harvest? (Quarter in photo for scale)

I have included photos, any advice or recommendations is much appreciated!
